Hide JSON Parse Errors in Express POST
-1
I have this little Express server:
var express = require("express");
var app = express();
app.use(express.json());
app.post("/hackme", (req, res) => {
if(!req.body.foo) {
return res.send({ error: 'oh no' });
}
return res.send({ lbxapi: '1.1' });
});
app.listen(3050, function() {
console.log("Express running");
});
When I send an invalid JSON POST body to the following server, I the full error stack like:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<title>Error</title>
</head>
<body>
<pre>SyntaxError: Unexpected string in JSON at position 18
<br> at JSON.parse (<anonymous>)
<br> at parse (/home/jan/Desktop/linkbox_beta2_github/code/experiments/node_modules/body-parser/lib/types/json.js:89:19)
<br> at /home/jan/Desktop/linkbox_beta2_github/code/experiments/node_modules/body-parser/lib/read.js:121:18
<br> at invokeCallback (/home/jan/Desktop/linkbox_beta2_github/code/experiments/node_modules/raw-body/index.js:224:16)
<br> at done (/home/jan/Desktop/linkbox_beta2_github/code/experiments/node_modules/raw-body/index.js:213:7)
<br> at IncomingMessage.onEnd (/home/jan/Desktop/linkbox_beta2_github/code/experiments/node_modules/raw-body/index.js:273:7)
<br> at IncomingMessage.emit (events.js:182:13)
<br> at endReadableNT (_stream_readable.js:1091:14)
<br> at process._tickCallback (internal/process/next_tick.js:174:19)
</pre>
</body>
</html>
I dont want to user to see this. How can I hide it? An answer would be accepted that changes my server's code so that I dont see it anymore. Thank you!

Thanks to the comment by Ariel Alvarado (= using default error handler), I can answer my own question:
var express = require("express");
var app = express();
app.use(express.json());
// added this error handler
app.use(function (err, req, res, next) {
console.error(err.stack)
res.status(500).send('Something broke!')
});
app.post("/hackme", (req, res) => {
if(!req.body.foo) {
return res.send({ error: 'oh no' });
}
return res.send({ lbxapi: '1.1' });
});
app.listen(3050, function() {
console.log("Express running");
});
